How are we different?
Our calcium is obtained from the sustainable extraction of calcified Atlantic Lithothamnium red algae. Due to its organic structure, our phytocalcium has particularly good bioavailability.
Atlantic Lithothamnium red algae has an exceptionally high concentration of naturally bound calcium (32%). The calcium is present in the form of calcium carbonate and is embedded in a mineral complex with magnesium. During its growth, the algae absorb these from the seawater and form their cell structures. After dying, the algae body calcifies into a finely porous, skeleton-like structure and sediments separately from the younger algae on the seabed of the Atlantic Ocean. In various locations, these sediments can eventually be sustainably harvested.
Our phyto-calcium consists of 100% natural calcified Lithothamnium calcareum from Iceland, which is harvested, cleaned and milled according to HACCP and ISO 22000:2018 standards, ensuring processing with minimal heavy metal and microbiological values, resulting in a red algae powder of maximum purity and compatibility. As a result, the heavy metal values, despite the origin from the seabed, are significantly below the European limits.
For the capsule shells we use custom-made HPMC capsules that, unlike most other HPMC and pullulan capsules on the market, are 100% free from controversial additives such as carrageenans and PEG. We then package this product in environmentally friendly amber glass.
Our commitment to uncompromising quality & purity:
- Premium active ingredients as pure isolates & directly sourced from leading global producers
- All formulations crafted exclusively from selected individual raw materials
- Our commitment: zero unnecessary additives, technical excipients or chemical extraction agents
- Voluntary declaration of all non-mandatory ingredients
- Where additives are necessary, preference is given to valuable natural ingredients
- Capsule shells entirely free from carrageenan & PEG
- Systematic quality testing conducted by independent laboratories
- Packaged in amber glass or premium aroma-protective zipper bags designed to protect against oxidation & contaminants
- All products entirely free from magnesium stearate, nanoparticles (without legal exceptions), GMOs, artificial colours & flavours, titanium dioxide
- Added sugar & sweeteners: used only where required for functional or product-specific reasons
Effects
Calcium
Calcium exists in greater quantities than any other mineral in the human body. 99% of bodily calcium is located in the bones and teeth, where it provides structural stability and strength. Additionally, calcium plays a role in various cellular processes, including energy production, blood clotting, signal transmission between nerve cells and the excitation of muscles and nerves.
Plant-Based Calcium Carbonate with High Bioavailability
The plant-based calcium found in calcified Lithothamnium red algae is organically formed calcium carbonate, which differs fundamentally in form and fine structure from calcium carbonate from inorganic sources such as limestone. Unlike limestone, algae calcium is finely porous, which increases the surface area and thus the solubility and bioavailability of the calcium carbonate.
Phytocalcium from Red Algae
In addition to highly bioavailable calcium, Lithothamnium red algae naturally contains a range of other minerals and trace elements absorbed from seawater. Magnesium is present in particularly significant quantities.
According to the European Food Safety Authority (EFSA):
Calcium contributes to:
- Normal blood clotting
- Normal energy metabolism
- Normal muscle function
- Normal signal transmission between nerve cells
- The normal function of digestive enzymes
- Plays a role in cell division and specialisation
- The maintenance of normal bones
- The maintenance of normal teeth
- Reducing the risk of bone mineral density loss in postmenopausal women. Low bone mineral density is a risk factor for osteoporotic fractures
- Normal growth and bone development in children

Product Details
Our in-house production guarantees uncompromising purity and quality. Production, bottling and encapsulation take place in the EU according to our own rigorous specifications and in strict compliance with HACCP, GMP and ISO 22000:2018 standards.
Bespoke liquid formulations, (functional) foods for athletic and daily performance and select exclusive items are produced as high-grade custom preparations by chosen partners who share our commitment to quality, adhering strictly to HACCP, GMP and ISO standards.
In line with our True Clean Label philosophy, we refrain from using artificial additives, colourants and preservatives intended to standardise product appearance. Consequently, formulations containing natural botanical extracts and plant-based raw materials may display subtle batch-to-batch colour variations. These variations stem from natural factors such as harvest timing (seasonal differences between early and late harvests), origin (geographical soil and climate fluctuations) or processing dynamics (variations in particle grind size). Such natural shade shifts may also occur in our plant-based or compressed tablets formulated with premium acacia fibre or nanoparticle-free cellulose and do not constitute a defect in quality.
Laboratory Tests
The purity of our formulas is important to us. This is why we have both our raw ingredients as well as our finished products extensively tested by independent laboratories to confirm purity and active ingredient content. Here, we have provided the results of some of the tests carried out on this product.
